EARLE C. MGKINNIE, OF CHICAGO, ILLINOIS, ASSIGNOR TO 'NATIO NALlX-BAYREFLECTOR CO., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

COMBINED DIRECT AND INDIRECT LIGHTING FIXTURE.

Specification of Letters Patent.

Application filed June 20, 1917. Serial No. 175,777.

To all whom it may concern:

Be it known that I, EARLE C. MCKINNIE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Combined Direct andIndirect Lighting Fixtures, of which the following is a specification.

My invention relates to that class of fixtures which possess theadvantageous features of total indirect lighting, but which will alsoprovide direct illumination so as to remove the artificial appearance ofa room lighted by total indirect means.

My invention has for its object to accomplish the foregoing in a simpleand inexpensive manner.

My means of accomplishing the foregoing objectsmay be more readilyunderstood by having reference to the accompanying drawings, which arehereunto annexed and are a part of this specification, in which:

The figure is a vertical sectional view of a fixture showing myimprovement.

Similar reference numerals refer to similar parts throughout the entiredescription.

As shown in the drawings, the fixture consists of an annular member 2,which supports a translucent bowl 3, the member 2 being suspended fromthe ceiling by chains 4, secured to the usual ceiling canopy 5. Anelectric light bulb 6 is suspended within the member 2, and above areflector 7 which is somewhat the shape of an inverted cone, which isadapted to direct the light rays upwardly and outwardly toward theceiling,-

whence it is redirected to the working plane. lVithin the spaceintermediate the translucent bowl 3, and the reflector 7 I mount anauxiliary electric light bulb, preferably about a 15 watt base lamp,either clear or frosted. The connections for this bulb 8, may be bymeans of a socket 9, mounted inside of the reflector 7 or it may befound desirable to carry the wires along the outer surface of thereflector. Under some circumstances, it may be found desirable toprovide a closure 10, for the opening between the top of the reflector 7and the annular Copies of this patent may be obtained for five centseach, by addressing the member 2, to keep the dirt and dust out of thetranslucent bowl 3.

Having described my invention what I regard as new and desire to secureby Letters Patent is:

1. In a device of the character described, the combination with a sourceof light, of an annular member, a translucent bowl, a conoidal reflectorwhich directs the light flux upwardly and outwardly, and which extendsdown into the bowl, an auxiliary source of light secured to the point ofthe reflector intermediate the reflector and the bowl.

2. In a device of the character described, the combination with a sourceof light, of an annular member, a translucent bowl, supported by saidmember, a conoidal reflector Patented Oct. 14, 1919.

which directs the light flux upwardly and outwardly, an auxiliary sourceof light intermediate the reflector and the bowl, a

socket secured to the reflector in which said source of light ismounted, and means to suspend said device from the ceiling.

3. In a device of the character described, the combination with a sourceof light, of an annular member, a translucent bowl, an inverted conoidalreflector which directs the light flux upwardly and outwardly, the pointof which extends into said translucent bowl, an auxiliary source oflight intermediate the reflector and the bowl, a socket secured to saidreflector in which said source of light is mounted, and means to closethe space between the top of the reflector and the annular member.

4:. In a device of the character described, the combination with asource of light, of an annular member, a translucent bowl, supported bysaid member, a reflector which diroots the light flux upwardly andoutwardly,
